Steps to test threshold seal

1. Close door on a piece

of paper placed over

the threshold.

2. Pull paper between

the sweep of the door

and the threshold.

3. If the threshold is properly

adjusted, you should

feel some tension,

but if the paper tears, the door’s seal is too tight. If there

is no tension on the paper, the door’s seal is too loose.

To properly adjust the threshold seal if it is too tight.

1. Adjust rail by turning screws evenly a 1/2 turn.

2. Repeat seal test. If paper does not slide beneath door

with a feeling of tension, repeat Step. Re-test seal.

3. Continue testing threshold until it is properly adjusted.

To properly adjust the threshold seal if it is too loose.

(WARNING: Do not increase height by more then 1/4")

1. Adjust rail by turning screws evenly a 1/2 turn.

2. Repeat seal test. If paper does not slide beneath door

with a feeling of tension, repeat Step. Re-test seal.

3. Continue testing threshold until it is properly adjusted.

Step 6 : Install Dead Bolt and Strike Plates

Step 8 : Caulk Doorway

Figure 26 : Screws fasten the latch plate to the door slab.

Install the dead

bolt strike plate

at the correct

location, per the

manufacturer

installation

detail (Figures

26 and 27).

Figure 27 : Screws should connect the dead bolt plate to the stud.

Step 7 : Insulate

Score shims with a utility knife and snap

the shims along the score. Trim any

excess with the utility knife. Insulate

around the top and sides of the door

unit in the cavity between the jamb and

the wall studs with berglass blanket

insulation (Figure 28). Install the interior

and/or exterior trim around the door.

Figure 28 : Insulate between the jambs and the wall studs all around the door.

Critical Point : The use of expandable type foam is not

recommended as it may cause the door jambs to warp;

this may leave the door inoperable or push the brickmould

away from the jamb.

Step 9A : Adjust Sill

Step 9B : Adjust Sweep

Figure 34 : U-channel sweeps are

adjusted to form a tight seal

with the sill.

Some door units are supplied

with a U-channel adjustable

sweep and these may be raised

or lowered to form a tight seal

with the xed sill. To adjust the

sweep, loosen the screws that

hold the sweep in place and

lower the sweep far enough to

create an airtight seal with the sill.

Once the sweep is positioned properly, tighten the screws by hand,

taking care not to over-tighten (Figure 34).

Figure 35 : The latch and dead bolt are installed per the hardware

manufacturer installation detail.

Your factory nished prehung unit comes with a color matched

wax pencil and marker. Follow these instructions to touch up

nail holes, cracks and other damages after installation of factory

nished jambs, brickmold, mullions and quarter round.

Wax Pencils / Fill Stick :

1. Work into the nail hole, crack or other blemishes

2. Wipe off excess with cloth as needed.

Stain Marker :

CAUTION : Contains mineral spirits which are harmful if

swallowed. Read manufacturer’s directions in full.

1. Shake marker well. Remove cap and depress tip gently a

few times on scrap paper or wood to start stain owing.

2. Apply stain to wood.

3. Wipe excess with cloth as needed.

4. Replace cap tightly and store pen lying at.

NOTE : Read manufacturer’s rst aid and warning information

prior to starting.

The nish on your Masonite AvantGuard exterior door is very

durable and tolerant of exposure to many common household

materials. If it becomes necessary to clean the door surfaces,

please use a mild detergent, warm water and a clean cloth.

Warranty

Warranties are available for most products. Please check with your

dealer or distributor for current warranty terms and conditions.

Trouble Shoothing

If it becomes apparent that there is some trouble with the operation of

the unit, the rst thing to check is the installation of the unit into the rough

opening. Check to insure that 1⁄8" gap across the top edge of door

panel and frame holds true for the entire width of the door opening AND

that weatherstripping is evenly compressed the entire height of the door

opening. Secondly, check that the two jambs are correctly aligned with

each other and that incorrect nailing on shims have not twisted the jambs.

Check all Critical Points to conrm that unit was installed correctly in

proper rough opening.

Step 5 : Shim and Fasten Step 5 : Shim and Fasten

Factory-Finished Door System

Because the inside of the jamb is not accessible, a 3/8" hole must be

drilled through the factory-nished exterior jamb, 1/4" deep at all points

where the door system is shimmed (three on each exterior side of a non-

operable panel, Figure 23). Drive the supplied 2-1/2" installation screws,

through the drilled hole in the exterior

thick (stop) section of the jamb, through the shims and into the studs

(Figure 24). Use the supplied caps to cover the holes in the

exterior jamb (Figure 25).

Figure 23 : Pre-finished

systems must have holes

drilled before screws

are installed.

Figures 24 and 25 : Drill holes through the exterior

jamb on factory-finished doors to install screws

and plugs.

Step 5C : For door with sidelites

Note: Units intended

for installation

in high velocity

windstorm regions

may require

additional points of

attachment. See

local retailer for

installation sheet

supplement.

Figure 20 : Install shims in the correct location and in the correct sequence.

Stand on the inside of the door and center the door in the opening.

Shim tightly at the bottom corners of the door unit

(Points A in Figure 20).

This will keep the door centered and the frame tight against the

sill. Shim the top of the frame, behind the latch-side jamb (Point

B in Figure 20). Install shims until there is a consistent 1/8" gap

between the top of the operating door slab and the frame header.

Shim at the top of the frame, behind the hinge-side jamb (Point C in

Figure 20) to hold the door tight in its position relative to the frame. The

door should operate freely with nothing but the shims holding it in place.

CAUTION : Do not open door panel greater than 30-degrees until

2-1/2" screws have been installed. (Points B, C, D, E & F in Figure 20).

From the outside and with the door closed, ensure that

the frame is in a straight vertical plane (not twisted). To

do this, check that the weatherstripping on the latch side

is evenly compressed along the entire height of the door

slab, without any pinching or gaps (Figures 8 and 9).

Once there is an even 1/8" gap across the top of the door slab and the

weatherstripping is evenly compressed along the height of the door slab,

proceed with the installation.

Shim at points D, E and F on the perimeter of the frame (Figure 20), until

there is an even 1/8" gap on both sides of the operating door slab.

Drive the supplied 2-1/2" installation screws, three on each exterior jamb

of a xed panel, through the exterior (stop) section part of the jamb,

through the shims and into the studs. Note: If the door is factory-nished

use the “Factory-Finished Door System” information for fastening

through exterior jambs.

For units with two non-operable panels: Typically long security screws

are used to install the dead bolt strike plate (Step 6).

For units with only one non-operable panel attached on the latch side

of the door : The second set of supplied screws are installed through

the thin (rabbet) section of the jamb using the vacant hinge screw holes

(Figure 21). Typically long security screws are used to install the dead bolt

strike plate (Step 6).

For units with only one non-operable panel attached on the hinge side

of the door : The second set of supplied 2-1/2" screws are installed

through the thin (rabbet) section of the jamb under the weatherstripping

through the shim and into the stud approximately 8" from the top and

bottom of the jamb (Figure 22). Shim just above and below the dead bolt

hole and drive the supplied 2-1/2" installation screws through the dead

bolt strike plate (Step 6).

When shims are properly installed, the frame should not move or

twist at all when the screws are tightened and counter-sunk, thus

maintaining the 1/8" gap. If there is any movement, loosen the

screws and shim tighter to maintain the 1/8" gap,

then re-tighten screws.

Figure 21 and 22 : The second set of supplied screws is installed

in the vacant hinge holes or under the weatherstripping.

Proceed to Step 6.

Caulk all four exterior corners and all around the brick or siding in

the following sequence:

caulk the sill on both latch and hinge sides from the edge 

of thesill crown along the edge where the sill and jamb or

brickmould meet (Figure 29)

Calfeutrer le bord avant du seuil, là où le seuil et 

le sous-plancher se rejoignent (Figure 30)

Figures 29 and 30 : Caulk the sill crown and the front of the sill.

caulk the top corners where the header and jambs meet, 

starting at the weatherstripping and working to the face of the

brick mould (Figure 31)

caulk the perimeter where the exterior trim meets the brick or 

siding trim (Figure 32)

If the door is center-hinged or has a sidelite, caulk around the

mullions where the mullions contact the sill and header.

Figures 31 and 32 : Caulk the jambs and the exterior trim.

Figure 33 : Raise or lower the sill by adjusting the sill screws. Some sills may

have covers over the adjusting screws. These covers must be removed prior to

making any adjustments.

Some door units are supplied

with adjustable sills, and these

may be raised or lowered to

form a tight seal with the xed

sweep on the bottom of the

door. This adjustment requires

a screwdriver with appropriate

screw bit. To increase the

height of the sill cap, turn

screws evenly along the rail.

Refer to the “Steps to test

threshold seal”. (Figure 33).

Step 10 : Install the Latch and Dead Bolt

1. Add a bead of caulk at both ends of sill cap where the cap

meets the jambs.

2. On door lock-side of cap, afx latch seal vertically to jamb on

top of caulk where jamb and cap meet. Push seal into caulk.

3. On door hinge-side of cap, afx hinge pad horizontally to jamb on

top of caulk where jamb and cap meet. Push seal into caulk.

For double doors: Test the threshold seal for the active and

passive doors. Once threshold seal is properly adjusted, afx latch

seal vertically so bottom of seal is resting where cap and both

doors meet. Remember to install hinge pads on both jambs.
